Ancient Underworld Dragon

Underworld dragons embody the pressure between tectonic plates, the heat behind geysers, and flash fires that ignite when the conditions are just right. Natural alchemists, they innately understand reagents and catalysts. While some research the effects of magic on material reactions, the majority of underworld dragons concentrate on building their hoards. They scour the world for carved gemstones and artifacts of precious minerals, both of which they see as distilled essence of earth's bounty.

Underworld dragons appear angular and sharp; their scales glow as if superheated from within, and their hair flickers like tongues of flames. An intense fire glows behind their gazes, suggesting they could ignite items with a mere thought, and their breath ripples the air as a testament to the heat contained within their bodies.

Countered by Water If the underworld dragon takes damage from a spell with the cold or water trait, the elemental magic of fire within them is momentarily dampened. Until the end of their next turn, they take a –1 circumstance penalty to attack rolls, their jaws Strikes don't deal fire damage, and also lose their sweltering heat aura. This limitation ends if the dragon uses Breath Weapon.
Fed by Wood When an underworld dragon is struck by a weapon made primarily of wood or affected by a spell with the plant trait, the dragon's internal fiery essences are stoked with the added fuel. Their breath weapon recharges, and the fire damage from the dragon's jaws increases by one die until the end of the dragon's next turn.

Dragon, Imperial

Related Groups Dragon, Forest, Dragon, Sea, Dragon, Sky, Dragon, Sovereign
Imperial dragons, namesake of the Dragon Empires and guardians of Tian Xia before humanity arrived, embody five strengthening and counteracting forces. Unlike other true dragons, imperial dragons dive deep into human affairs. Some remain secretive, posing as reclusive hermits, while others keep a high profile, openly ruling factions. Tian cultures in turn venerate the dragons, depicting gods in the form of dragons or claiming ancestry from them. Not all are adored, for plenty of these creatures act wickedly.

Draconic Cycles

Five elements underpin the magical powers of imperial dragons, influencing their relationships to all things and, especially, to others of their kind. These elements interlink in two cycles. In the first cycle, each element feeds one other: wood feeds fire, fire feeds earth, earth feeds metal, metal feeds water, and water feeds wood. In the second cycle, each element counters another: wood counters earth, earth counters water, water counters fire, fire counters metal, and metal counters wood.

Each imperial dragon represents one element and has four abilities related to the cycle. For example, the forest dragon—linked to wood—feeds fire, is fed by water, counters earth, and is countered by metal.

Shape-Changing Dragons

Imperial dragons are the most likely (and willing) of Golarion's dragons to take humanoid forms. The vast majority of them have the following ability, with the tradition trait matching the dragon's innate spells:

Change Shape Single ActionSingle Action (concentrate, polymorph, transmutation) The dragon takes on the appearance of any Small or Medium humanoid. This doesn't change their Speed or attack and damage modifiers with their Strikes, but it might change the damage type their Strikes deal (typically to bludgeoning).

Imperial Dragon Spellcasters

Each imperial dragon has a sidebar on spellcasting dragons of that kind. To make an imperial dragon spellcaster, remove the dragon's Coiling Frenzy and Draconic Momentum abilities and give them the spells outlined in their sidebar. You can swap any number of these spells with others from the same tradition, provided you keep the same number of spells for each level. You might also want to increase the dragon's Intelligence, Wisdom, or Charisma modifier by 1 or 2 to reflect their mastery of magic.

Imperial Dragons On Golarion

Imperial dragons are rarely spotted beyond Tian Xia, where some establish territories to amass power, while others follow their natural affinity to seek a place of comfort.
